---- Reported by monobugs@radeldudel.de 2004-07-26 10:09:04 MST ----

Description of Problem:

I wrote a console-app. This app utilizes the win32-call 
SetConsoleCtrlHandler to get notified about aborts, system shutdowns, ...

When I use mono to start the app and press ctrl+c mono pops up an error 
window 
"** ERROR **: file mini.c: line 6508 (mono_get_lmf_addr): should not be 
reached
aborting..."

On the same moment the program stops without getting notified of being 
stopped and on the console prints this error: 
"This application has requested the Runtime to terminate it in an unusual 
way.
Please contact the application's support team for more information."

Steps to reproduce the problem:
You need to compile the sample source to a console app, start it using 
mono and press ctrl+c in the console while it is running to get the error 
popup:
--- console sample app
using System;
using System.Runtime.InteropServices;

namespace Sam.CmdTestWait
{
 class MainClass
 {
  public enum XConsoleEvent
  {
   CTRL_C = 0,		// From wincom.h
   CTRL_BREAK = 1,
   CTRL_CLOSE = 2,
   CTRL_LOGOFF = 5,
   CTRL_SHUTDOWN = 6
  }

  private delegate bool ControlEventHandler( XConsoleEvent consoleEvent);
		
  [DllImport("kernel32.dll")]
  static extern bool SetConsoleCtrlHandler(ControlEventHandler e, bool 
add);

  private static bool Handler( XConsoleEvent consoleEvent)
  {
   return true;
  }

  [STAThread]
  static int Main(string[] args)
  {
   ControlEventHandler eventHandler= new ControlEventHandler(Handler);
   SetConsoleCtrlHandler( eventHandler, true);

   int countdown= 10;
   while (countdown>0)
   {
    Console.WriteLine( countdown+"...");
    System.Threading.Thread.Sleep( 1000);
    countdown--;	
   }
   Console.WriteLine( "time over");
   return rc;
  }
 }
}
--- end code

Additional notes:
Since this feature is using interop it might well be you don't care about 
this bug, or don't want to cover it since to capture console events you 
will need complete different approaches on Linux, so maybe this is no bug 
at all, but only a windows feature not working on mono.
But thats for the mono developers to decide, not for me.

The issue here is that SetConsoleCtrlHandler calls back to managed
code on a thread that we have not attached to. We don't/won't support this

about this bug.

The bug is fixed.
